I have this function in my solidity contract:

function requestRandomNFT(
        address minter,
        uint256 nonce,
        uint256 deadline,
        uint8 v,
        bytes32 r,
        bytes32 s,
        uint256 randomUint256
    ) external payable {
        require(block.timestamp <= deadline, "Request has expired");
        require(nonce == _nonces[minter].current(), "Nonce does not match expected value");

        bytes32 structHash = keccak256(
            abi.encode(
                _REQUEST_RANDOM_NFT_TYPEHASH,
                keccak256(
                    abi.encode(
                        minter,
                        nonce,
                        deadline
                    )
                )
            )
        );

        bytes32 hash = _hashTypedDataV4(structHash);

        address signer = ECDSA.recover(hash, v, r, s);
        emit Verified(signer, nonce, minter, r, s, v, signer);
        console.log("below this is signer");
        console.log(signer);
        console.log("below this is aithorizedAccount");
        console.log(authorizedAccount);
        require(signer == authorizedAccount, ERR_INVALID_SIGNER);

        bytes32 requestId = keccak256(abi.encodePacked(signer, nonce));

        _nonces[minter].increment();

        emit RequestedRandom(requestId);

        // Auto mint NFT
        mintNFT(minter, requestId, randomUint256);
    }

I used import "hardhat/console.sol"; to write logs to the console.

This is my minting code:

import { parseGwei } from 'viem'

// Function to get a signature for the random NFT request
async function signRandomNFTRequest(account, nonce, deadline) {
    const privateKey = "0x REST OF MY PRIVATE KEY";
    const wallet = new ethers.Wallet(privateKey);

    const domain = {
        name: "RandomReachDebug5Local",
        version: "1",
        chainId: 31337, // chainId for local node (Ganache or Hardhat)
        verifyingContract: "0x8464135c8F25Da09e49BC8782676a84730C318bC", // replace with your contract address

    };
    const value = {
        minter: account,
        nonce: nonce,

    const signature = await wallet._signTypedData(domain, types, value);
    const sig = ethers.utils.splitSignature(signature);
    console.log("Signature: ", sig);
    return sig;

export function useMintNFT() {

            const balance = await provider.getBalance(connectedAddrs);
            console.log("Balance: ", ethers.utils.formatEther(balance));

            const contractInstance = new ethers.Contract(randomReachDebug5Address, RandomReachDebug5Local.abi, provider.getSigner());
            console.log(`contract is set here: ${contractInstance}`);
            if (!sigData) {

                    const deadline = Math.floor(Date.now() / 1000) + 120; // 2 minutes from now

                    setSigData(sig);
                    const randomUint256 = ethers.utils.hexlify(ethers.BigNumber.from(ethers.utils.randomBytes(32))); // generating random uint256

                    const argsInUseEffect = [connectedAddrs, nonce.toString(), deadline, sig.v, sig.r, sig.s, randomUint256];
                    console.log("Args in use effect: ", argsInUseEffect);
                    setArgs(argsInUseEffect);
                } catch (error) {
                    console.error("Error fetching nonce: ", error);

    const { isLoading, isSuccess } = useWaitForTransaction({hash: data?.hash});

    const mintNFT = () => {

            write?.();

    return {
        mintNFT,
        isLoading,
        isSuccess,
        isError,
        error,

        prepareError,

}

So here's the weird thing... When I ran the minting code within a next.js app, I got this in my console for the hardhat node:

console.log:
    below this is signer
    0x2d0b2215d4e00807a6982877a9762ef41541ecef
    below this is aithorizedAccount
    0x1ab26702a8068a247bd33a9555dfef791d2bd68d

But the private key I used gives me the address 0x1AB26702A8068a247BD33a9555dfEf791d2BD68D when I test it in javascript with ethers.js, but solidity gives me 0x2d0b2215d4e00807a6982877a9762ef41541ecef ???

I used this script with const privateKey = "0x REST OF MY PRIVATE KEY":

const ethers = require('ethers');

function getAddressFromPrivateKey(privateKey) {
    const wallet = new ethers.Wallet(privateKey);
    return wallet.address;
}

const privateKey = "0x REST OF MY PRIVATE KEY";
console.log(getAddressFromPrivateKey(privateKey)); // This should log your expected address

This code gives me 0x1AB26702A8068a247BD33a9555dfEf791d2BD68D, but my solidity code gives me 0x2d0b2215d4e00807a6982877a9762ef41541ecef. That doesn't make any sense. Why is this happening?
